Application filed June 23, 1909. Serial No. 503,924.

.To all whom it 'may concern.

Be it known that I, Josiiri-r F. MURDocx, a citizen of the United States, residing at leys are peripherally concaved as shown and have their end portions cylindrical in form as at 7, 8, respectively, the end portions 7 of Dunlap, in the county of King and State of the controlling pulley 1 being also provided lashing-ton, have invented new and useful with sprocket teeth 9. On the standards 10 Improvements in F reight-Transhipping Apof the said pivotally mounted pulley platparatus, of which the following is a speciforms are vertically disposed rollers ll fication. which are at the ends of the said pulleys and This invention is an improved transhipextend above the saine, as shown. The axle ping apparatus especially adapted for use in shaft 12 of the controlling pulley 1 is here supplying coal from one vessel to another at shown as provided with a pulley 13 which is sea, but also adapted for use in transhipengaged by a belt la which connects it to a ping freight of any kind and for transpulley 15 on the power shaft 16 of a suitable ferring passengers from one vessel to anmotor indicated at 17 and which motor is other in cases of emergency and the said inmounted on the platform 3 and serves both vention consists in the construction, comto rotate the pulley l and to control the said biiiation and arrangement of devices hereinpulley so that the said pulley 1 may be after described and claimed. caused to rotate at any desired rate of speed In the accompanying drawings :-Figure or held against rotation as may be required 1 is an elevation of a transhipping apparawhen the apparatus is in operation. A pultus constructed in accordance with this inley 18 is here shown as mounted in bearings ventioii, showing the same in use for convey- 19 011 the deol of the Vessel B at a suitable ing freight, such as coal in sacks from one distance from the supporting pulley 2 and vessel to another.

The pivoted supporting platform for the Within the scope of my invention, the controlling pulley 1 is indicated at 3 and flexible endless carrier may be of any suitthat for the supporting pulley 2 is indicated able construction. For the purposes of this at 4, the pivots of the said platform being t specification it is shown as composed of respectively indicated at 5 and 6. The pulparallel side chains 27 and transversely disposed carrier rods 2S which connectisaid side chains together. In practice, these carrier rods are curvedso'that those on the upper lead of the carrier are bowed downwardly and those on the lower lead thereof are' bowed upwardly and hence the carrier rods of the upper lead' of the carrier will keep freight or commodities such asflled sacks in place thereon while traveling from one'vessel to the other. In practice, the endless.V carrier will be made of a number of sections of suitable length which may be connected together or detachedy at will to increase or decrease the length of the carrier as may bedesired and according to the distance between the vessels, and for the purposes of this specification, portions of two sections ofthe carrier are shown in Fig. 5a bolt rod Q9 being indicated in said figure to detachably connect the said sections together,;said bolt rod as will'be understood passing through and forming the pivots of certain of the links of the side chains. The lower lead of, the carrier runs on the anti-friction rollers 21. The Vertically disposed rollers 1l, 20, and 23 prevent the endless carrier from` slipping from the pulleys and anti-friction rollers. Links of the side chains of the endless carrier are engaged by the sprocket teeth of the controlling pulley 1 and hence when the said pulley is set in mot-ion the endless carrier is caused to move so that its upper lead travels from the vessel B to the vessel A and hence sacks or other articles which are placed on the endless carrier of the vessel B are delivered into the upper end of a receiving chute D on the VesselA. Owing to the pro- Vvision of the slack bight in th'e'lower lead of the carrier and the vfact that the said carrier may be readily slippedv 0n the pulleysY .all conditions so that the apparatus may esseci Q, 18, the carrier will accommodate itself to the rolling of the vessels and the taut, upper lead thereof will be maintained under be operated while the vessels are in motion and in a sea-way. The pivotal mounting of the platforms which carry the pulleys also enables the endless carrier to accommodate itself to the motions of the vessels.

That is claimed is,:--

The combination with two spaced vessels, a pivoted platform upon one of the vessels, a controlling pulley upon the platform, means for rotating the pulley, anti-frictional rollers arranged adjacent each side of the pulley and projecting thereabove, a directing pulley positioned adjacent the end of the vessel, anti-frictional directing rollers adjacent to and extending above each face of this pulley, the second vessel having a pivoted platform, a pulley upon said platform, anti-frictional rollers adjacent to and extending above said pulley, a second pulley positioned forward of the platform and at one end of the said second vessel, directing rollers for this pulley, a third pulley mounted to the rear of the platform of the second vessel,` directing rollers for this pulley, an endless chain for all of the pulleys, the upper lead of the carrier being positioned upon the upper faces ofthe pulley, the lower lead adapted to lie loosely between the two bodies and being of a sufficient weight and slackness to retain the upper lead approximately taut.

In testimony whereof I aflix my signature in presence of two witnesses.
